PATENT OFF CARL A. IQERISSEN, OF WASHINGTON, DIS'I'RIC'I. OF COLUMBIA.

TYPE-WRITING MACHINE.

To all whom it may concern: 1 i

Be 1t known that I, CARL A. Jonnrssex, a citizen of the United States, residing in the city of Washington, District of 'Columbia',

have invented certain new and useful Improvements in Type-Writing Macl1ines, of

which the following is a specification.

This invention relates to the type bar segments of writing machines having detachable type bars.

The principal object of the invention is to render it feasible to take out and replace individual bars without the necessity of constructing the type bar in such a manner that it is liable to become accidentally displaced from its position on the segment.

The principal feature of the invention consists in providing recesses at intervals along a fulcrum rod upon which the type bars are mounted, the recesses corres onding to the intervals at which the type are areplaced in the segment. The ty e bars have open slots, the-openings in t e slots being too small to permit them to pass over the body of the fulcrum rod, while sufficiently large to pass over the slotted or recessed portions of the fulcrum rod. The latter may be moved endwise to secure the bars after they have been placed thereon.

In the accompanying drawings, Figure 1 is a rear elevation of t e type bar segment showing the fulcrum rod in osition for attachment of the t e bars t ereto. Fig. 2 is a sectional side e evation of the type bar and segment. Fig. 3 is a view, similar to Fig. 1, but showing the fulcrum rod moved intoposition to lock the type bars, and there secured by a'screw. Fig. 4 is a viewv of the fulcrum rod. Fig. 5'illustrates the manner of placing a type bar uplon the rod. Fig. 6 is an enlarged view to s ow the pro ort-ions of the different parts of the rod and t e opening in the type bar slot. Fi 7 shows the rod recesses asbeveled for t e purpose of camming or lifting the bars onto the unrecessed or body portions of the'rod;

Bars 1 carrying types- 2 are mounted in radial'slots 3 formedlin a segment .4, the bars striking rearwardly against a platen 5. The bars have slots 6, Wherebythey are-"fulcrumed upon arod 7 the latter curved and seatedina groove 8 mthe segment.

The bar is formed at intervals with, re-

cesses or1cutawaysu9', formed preferably on.

both the concave and the convex sides of the rod, as shown; and every bar has an opening;

I 10 into the slot 6, said opening too small to permit the bar to be slipped on or off the uncut, body portion of the rod 7, see Fig. 6; i but large enough to pass. over any recessed 1 portion of the rod. In assembling the type bars, the rod 7 is placed in the liig. 1 position, and the bars l all inserted in the slot 3. Then the bar 7 is i moved endwise to the left, as at Fig. 3, so l that the body or uncut portions of the rod are engaged by the type bar slots 6 the re- 1 cesses 9 occupying positions between the segment slots 3. It is now impossible for any 5 bar to come off from the rod. The latter is locked in its bar-locking position by means of a screw 11', the head'of which catches upon the bar.

When it is desired to take out any bar, it is only necessary to loosen the screw 11, and move the rod, 7 t0 the right to the Fig. 1 position, when the bar may be readily sli ped off. p

f desired, the recesses 9 in the rod may be formed with beveled sides 12, to cam or lift the bars onto the body portions of the rod 7, during the endwise movement of the latter. By reason of this bevel 12,it becomes impossible for the type bars by falling into the recesses 9, to lock the rod against endwise movement.

stance the recesses 9 may be omitted on either the inner or the outer side of the rod 7, and the opening 10 made a trifle larger to correspond.

Having thus described my invention, I claim:

1. In a typewriting machine, the combination with a series of type bars having open slots, of a segment havingradial slots to receive the type bars and having an endwise shiftable fulcrum bar for said type-bars; the

. fulcrum rod being formed with recesses, one for each type bar, at intervals corresponding to the intervals between the segment slots; the opening in each ty e bar slot being too small to pass over the body of the bar, but large enough to pass over a' recessed portion of the rod; whereby the bars may be assembled upon the fulcrum rod, and the latter may then be moved endwise to lock the type bars against accidental displacement.

I -2. In a typewriting machine, the cpmbina- .tion with a series of type bars having open 'slots, ofa segment havin radial slots to receive the type bars and' aving an endwise Variations-may be resorted to, as for inof t e bar; means being provided to lock the fulcrum rod in bar-locking position.

3. In a typewriting machine, the combination With a series of type bars having open slots, of a segment havin radial slots to receive the type bars and iaving an enclwise shiftable fulcrum bar for said type bars; the

fulcrum rod'being formed with recesses, one X for each type bar, at intervals corresponding to the intervals between the segment slots;

.the opening in each type bar slot being too small to pass over the body of the bar, but

large enough to pass over a recessed'portion of the bar; the recesses in the fulcrum rod having beveled sides to enable the rod during its longitudinal movement to jcam or lift the type bars onto the body portions of the rod.

4. A curved fulcrum rod for a system of type-bars, recessed at intervals corresponding to' the spacing of the bars from one another.

5. A curved fulcrum rod for a system of typebars, recessed at. intervals corresponding to the spacing of the bars from one another; each recess formed with a bevel for the purpose specified.
